Additive manufacturing Technologies

The additive manufacturing technology developed for depositing concrete is one of the most common and well-developed for construction. Concrete is used in large-scale 3D printers to create large-scale structural elements such as walls and roofs with complex and custom shapes [1].

Additive Manufacturing (AM) with concrete , also known as 3-D Concrete Printing (3DCP) and more recently Additive Construction (AC) with concrete , is an emerging and rapidly evolving technology in the construction industry.

Concrete Additive Manufacturing

Explore how concrete additive manufacturing is reshaping construction. Discover its methodologies, benefits, challenges, and future trends. 🏗️🔬

One of such methods being explored currently, both in academia and in construction practice, is the additive manufacturing of concrete (AMoC). Albeit a steadily growing number of researchers and private enterprises active in this field, AMoC is still in its infancy.

3D Concrete Printing Explained

What is 3D Concrete Printing? 3D concrete printing is a subset of additive manufacturing that involves the gradual layering of concrete material to construct buildings or structural components directly from digital models.

This paper aims to present the applicability and possible fabrication strategies of concrete additive manufacturing to integrate concrete additive manufacturing on the component level.

Systematic review on 3D concrete printing technology ...

Binder jetting, an additive manufacturing technique used in 3D concrete printing, precisely bonds powder particles by depositing a liquid binder. This process allows for the accurate fabrication of intricate and detailed shapes [102, 103].

ASTM International's additive manufacturing technologies committee (F42) is developing a suite of proposed standards that will be used for quality assurance and quality control of materials and components used for additive construction with cementitious materials.

Additive Manufacturing of Concrete

Numerous challenges are being faced by the construction industry for implementation of Additive manufacturing of concrete to a large scale due to the scarcity of information available w.r.t this technology.

In recent years, significant development observed in the context of additive manufacturing in the construction sector and many printing methods for the replacement of OPC blocks of cement and concrete adopted during practical construction project development.
